Question 1

On a bright and sunny day, the intensity of solar radiation on the Earth's surface is 1 000 W/m². If the average wavelength of the sunlight is 500 nm, how many photons are incident on a square meter of the Earth's surface per second?

Question 2

Suppose we use optical radiation (λ = 500 nm) to determine the position of the electron to within the wavelength of the light. What will be the resulting uncertainty in the electron's velocity?
